Quantitative cutting method for bar machining

The invention belongs to the field of automatic machining, and particularly relates to a quantitative cutting method for machined bars. Quantitative and variable-length precise cutting of the machined bar is achieved according to the machining requirement of a user and the specified quality; decoupling the measurement and cutting process, and carrying out modular cutting; the cutting precision is flexibly controlled according to the machining requirement of a user, and the effect of controlling the precision is achieved by controlling the sampling frequency. Diversified machining requirements can be met, and an automatic cutting system is established. 本发明属于自动化加工领域，具体说是一种面向加工棒料的定量切割方法。本发明根据用户的加工需求，按照指定质量实现加工棒料的定量不定长精确切割；解耦合测量与切割过程，模块化切割步骤；根据用户的加工需求灵活控制切割精度，通过控制采样的频率来达到控制精度的效果。本发明可以满足多样化的加工需求，建立了自动化切割系统。
